To all whom it may concern: Be it known that L'JAcoB ate proved Construction .of Reenforced -;Concrete Poles, of which .the following .is a specification.

My invention has reference to improvements-in reenforced concrete structures and it is particularlydesigned to provide ;an:improved ,ree'nforced cement pole that isespe- :cia'lly adapted for telephone and telegraph service, and primarily my said invention has for its purpose the provision of an improved pole of the character stated, of a relatively simple and economical construction, of light weight and maximum efficiency.

Another object of my invention is to provide a plastic poleIstructureinwhich ,the

rein-forcing elements include acentral com-' bined anchoring and reinforcing means, that is especially designed for the convenient and positive attachment of stay members and for. so supporting the entire reenforced or .metallic structure of the pole that the said structure may be conveniently sustained withinythe mold box during the operation.

ln its complete ,make up my improved reenforced concrete pole embodies the, peculiar features of construction and novel arrangement of parts, all of which will be fully explained in the following detailed description of thestructural portions thereof, specifically mentioned in the appended claims, and illustrated in the accompanying drawings, in which;

central core formed of a T-shaped metal member 10 which is of such-le'ngth ,thatit" extends from endto'end of the pole.

' Tothe fiat side .1 of the member IOiare I V secured (preferablyat every six feet on'the lengthof the-pole) a series of ffla't steel'cross reinforcing arms Zand these; are securedby r1vets 3 -3 that pass throughthe said cross arms and theoppositeedgesjoftheifiat I side l'of the metal core or reinforcing memher-"1O as isbest shown in Figuretj .byrefi ere'nce to which it will alsjojloev observedgthat at each of the crossimembers or iarmsl2'a' supplemental ,member ,20 is bolted-to the angle {flange 11 ofithe T-shaped memberlO that extends into theang'le Aor" rearwardly projected flange portion 140 of the concrete body 1 that is shaped *into the desiredTform when pouringkthe'concrete into a suitably prepared mold box, having-a cross section shape as is clearly shown in Figure. 6fof; theidrawings. 1

When applying the portion the upper end of the T-shaped cen-' tral or metal core for a suitable 'distan'ce'is left exposed; that is, free of plastic'cover ing, to prov-idefifor conveniently attaching the cross arms,88 thatcarry theftelephone or telegraph wire insulators and which are attached by eye bolts. 9' that uta'ke around the T-shapedmember lO nd are clamped outer or plastic body to the said cross arms 8, ,through which-the threaded ends of the said bolts pass ajndvto which they are secured bfythe clamp nuts .6 as i l arly shown in iguree.

The several horizontalreinforcing I hers 2 are joinedby longitudinally extending wires 15, two sets of such wires being provided for the fiatface o'f thepole' and a' single set; of such-wires .forithe rib 'or flange {portion of thepole, as is best shown in Figure 20f thedrawings, by reference to which it will also be observed that the Wires 15, as they pass from one of'the cross members 2 to 'the next cross member 2 .are themselves; crossed and twisted togethergas at 25, and the sai'd wires are passed over the flatside of the front cross memberv 2 and likewise across the supplemental .jarlns 20 and lacedthrough apertures;2l22 in the said arms as shown.

16,16 designates supplemental reinforce Wires that extend straightway from the top to the bottom of the pole, and which are laced through apertures 21-22 in the outer and inner ends of'all of the front cross arms 2, two straight reinforce wires 18-18 being extended along the outer and inner edge of the webb or flange 11, the said wires being laced through apertures 1919 at the outer and inner ends of the supplemental or laterally extended arm 20 as shown.

The cement pouring form indicated in Figured may be of wood or steel and its shape makes it easy to place the fabricated reinforcement in place by simply hanging the said reinforcement structures within the form. r

Furthermore the arrangement of the form and the reinforcement structure makes it possible to keep the aforesaid reinforcement always in sight during the pouring of the concrete thus makin it easy to correct any misplacement thereof.

The box or form may be placed on benches or on the ground and the entire outer body of the pole to be quickly poured of the wet mixture, thereby insuring the density and strength of theconcrete without tamping or I turn it over and lift it off the completed pole, it then being ready for re-use.

At suitable places the form or mold box is provided with fillers to produce the usual shape of step braces 30, see Figure 8.

When building my improved cement pole structure, for example a thirty foot pole as indicated in the drawings, the width of the arms at the base is ten inches tapering to seven inches at the top, the small front arms being half as large as the wide arms to equalize proportion.

In my construction of cement pole the same has been designed to develop a maximum of'rigidity with the necessary amount of cement to thereby materially reduce the cost of the concrete poles. Y

' From the foregoing description taken in connection with the drawings, the complete construction, the manner of building my poles and the advantages of its use will be readily apparent of those familiar with the construction of and the handling of poles of the type to which my invention relates.

What I claim is:

1: A pole comprising a cementitious body, a central T-shaped metal standard imbedded centrally of and extending lengthwise of the said 'cementitious body, cross members secured to the flat face of the standard at intervalsalong its imbedded portions, other stay wires being disposed at right angles to the first mentioned stay wires, the saidother stay wires interlacing the members attached to the web of the standard and projected at right angles with respect to the front cross members. r V

2. A pole comprising a cementitious body, a central T-shaped metal standard imbedded centrally of and extending the full length of the said cementitiou's body, cross members secured to the flatface of the standards at intervals along its imbedded portions, other members secured to the web or flange of the standard and projected at right angles to the cross members on'the front face of the said standard and which are imbedded in the body portion, stay wires that extend from the top to the bottom of the body and are interlaced with the cross members attached to the front face of the T- shaped standard and other stay wires that extend from the top to the bottom of the body and interlacing the members attached to the flange or web of the standard, and further stay wires that extend from the top to the bottom of the body and engage the outer ends of the members attachedto the front and to the angled portions of the standard.

3. A pole comprising a cementitious body of a substantially T-shaped :metalstandard imbedded centrally of and extending the full length of the cementitious body, cross members secured at intervals across-theflat faceof the T-shaped standard, other members attached to the web or'T-sh'aped standard and projected at right angles to" the "front cross members, sets of stay wires that extend the full length of the cementitious body which lace through the aforesaid front'cross members, each of said sets of wires being twisted intermediate ofeach pair of cross members, like stay Wires extending from the top to the bottom of the cementitious body and laced through the members attached to the flange of the T-shaped body, said wires bein crossed and twisted at points intermediate of the standard, the saidstandard being extended upperwardly beyond the body and provided with means for attaching cross arms thereto. 1
